Abstract
Construction and psychometric analysis of a questionnaire for the evaluation of public transportation. The aim of this work has been the construction and psychometric analysis of a questionnaire for the evaluation of the urban bus system from the user perspective. Two studies have been carried out. In the first study, an initial version of the questionnaire with 25 items was administered. Through psychometric analysis the number of items was reduced to 16. A representative sample of the urban Galician population participate in the second study. It has been found that those 16 items could be grouped into 6 statistical factors, which comprise the following urban bus system relevant aspects: bus stops, information to users, timetable fulfilment, bus-drivers' professionality, service sufficiency, buses condition, special populations conditioning, and service satisfaction. Scale internal consistency and validity values were .8410 and .68, respectively.
